Why does the Changan Karvaan engine overheat frequently in Pakistans hot weather?

Many Karvaan users report overheating problems during summer, especially in cities like Lahore, Multan, and Karachi. Is this a design flaw in the cooling system, o r does it relate to the quality of coolant and radiator used locally?

Overheating in Changan Karvaan is common during summer, especially in cities like Lahore, Multan, and Karachi. The causes include:

Undersized radiator for extreme temperatures

Use of low-quality o r tap water instead of coolant

Weak cooling fan motors

Neglected maintenance

It’s not necessarily a design flaw but rather a mismatch between the vehicle’s cooling capacity and Pakistan’s harsh climate combined with poor local maintenance standards.
